Be it known that we, IVLLLIAM MILLAR DEUTsOH, of Elizabeth, in thecounty of Union and State of New Jersey, and CHARLES C. KANOUSE, ofNewark, in the county of Essex and State of New Jersey, have invented anew and useful Improvement in the Manufacture of Celluloid-CoatedDrum-Heads, of which the following is a specification.

Our invention relates to the manufacture of drum-heads; and it consistsin treating heads in a crude or finished state, of any materials ofwhich heads may be made, on one or both sides, with a coating ofcelluloid or other pyroxyline, and by any common process; and in doingso we render them water-proof, so that they will not be affected bychange of air or temperature, and can therefore be used the same in wetor dry weather, as there will be no loosening or shrinking in either,and when once tightened will remain the same, and need not be loosened.The sound is much improved and the goods can be made at less cost, ascheaper material may be used for the base, and yet we make an article ofgreater value.

We claim In the manufacture of drum-heads, one or both surfaces treatedwith a coating of celluloid or other pyroxyline, substantially as andfor the purpose specified.
